<h1>getchar function </h1>
<hr>

<p>
<b>getchar</b> is used to read data from the keyboard (
<a href=../MISC/stdfiles.html>stdin</a>). Effectivly
it is a <b>fgetc(stdin)</b>.<p>
The problem with this function is that the characters are buffered until 
RETURN is hit! This means that <b>getchar</b> does not see the characters 
until the user presses return. The non standard function <b>getche</b> 
gets around this problem and sees each character as it is pressed. 
I have not been able to produce the same function on Linux. 
The nearest I can get is by using 'curses' but it keeps clearing the screen!

<pre>
Library:   stdio.h

Prototype: int getchar(void);

Syntax:    ch = getchar();
